In class we are now working on "work" which is the change in energy. I took a picture of my speakers to display work. I chose this because it was unique and I don't think people realize what is happening to make sound. Something is working when it is working against a force. For instance if you were to just hold a book in one place it would not be considered work. Now if you were to move your arms up and down it would be work because it would be working against the gravitational pull. For the speaker scenario, the speakers don't look like there doing much but it is. When it makes noise and music the speakers work against air resistance which create different frequencies.
I never thought of sounds being considered as work, pretty nuts
ReplyDeleteYeah, I learned that having sound makes the object lose energy from Mr. Blake. What an interesting explanation— you really went into detail. :)
